APAR PJ42695 - z/TPF HTTP Server Enhancements (PUT12) z/TPF HTTP Server support has been updated, providing the following enhancements: HTTP Server support will now receive HTTP requests that use chunked transfer encoding and trailers. HTTP requests that have a Transfer-Encoding: header with a value of "chunked" included will result in the HTTP server support waiting to receive the "chunks" of the HTTP request body sent by the client. The HTTP server support will construct a single, contiguous HTTP request body from... [More]

The IBM Tivoli Monitoring Agent for z/TPF V1.1.2 is available from the TPF Family Products: Tools web page and adds support for z/TPFDF data collection counters, as well as a number of additional updates and fixes. APAR PJ42742, and prerequisite APAR PI30702, enhance continuous data collection (CDC) to include z/TPFDF data collection counters. This support provides you with the ability to monitor z/TPFDF API activity in an IBM Tivoli Monitoring environment. This enhancement can provide insight into z/TPFDF API activity in... [More]
The Master the Mainframe contest started last October is winding down with the final countries participating from the Middle East and Africa. This was the first year that region of the world participated, so the international outreach continues to grow! You can find details here: http://www-03.ibm.com/systems/z/education/academic/masterthemainframe/contest/mea.html As a reminder, z/TPF is included in this contest with a challenge revolving around the use of JSON to access z/TPFDF data. More details are found in a... [More]
APAR PJ43124 originally solved a specific problem reported to fix possible OSA-Express connection failures, but we have now discovered that there are other and more serious exposures (for example, core corruption that can cause an outage) that can be prevented by applying PJ43124; therefore, we strongly suggest all z/TPF customers apply PJ43124. See Service Bulletin 186 for additional details.

z/TPF customers use control unit copy services like IBM® Global Mirror as part of their disaster recovery processes to copy updates from the primary site to the secondary (disaster recovery) site. By default, control unit copy services mirror all updates that are made at the primary site to the secondary site. Some of the updates, however, represent transient data where the data is either short lived or is always initialized if z/TPF is IPLed at the secondary site. For example, certain types of short term pools or session login... [More]
Bob’s application is taking a dump because the application is writing in protected storage. Bob identifies where the application issued a cinfc, so the application should be allowed to write to protected storage. Bob is unsure why he is taking this dump. Bob could read the PSW, to find out what the PSW key is, but that would be cumbersome. With the new and improved ECB Summary view, Bob can easily follow what the PSW key is as he steps through his application. Bob opens up the ECB Summary view, then the Instruction Detail... [More]
z/TPF customers have expressed interest in exchanging messages with Linux systems. One common question that has been coming up is whether to use distributed (x86-based) Linux, or Linux on z in an LPAR next to the z/TPF LPAR. One factor important to many customers is latency so analysis was done to understand the network latency between these two configurations. The testing was done on an zEC12 machine comparing the latency from a z/TPF LPAR to a Linux on z LPAR in the same zEC12 machine sharing an OSA card to the latency from... [More]
Interested in what academia is doing to provide you with students in the enterprise computing arena? Marist College in Poughkeepsie, NY provides you with that opportunity. They have a FREE conference scheduled for June 14th-16th, 2015 where companies like yours can find out what is going on in the enterprise computing community and influence future programs. Marist and other colleges want to hear from you about your needs. Please consider attending the conference.
A defect in the channel microcode was reported in environments where High Performance FICON® for z Systems™ (zHPF) is enabled and the logical partition (LPAR) is set to ESA/390 TPF mode. The fix is under development to address this issue with ESA/390 TPF mode. Before you enable zHPF, set your LPARs to ESA/390 mode to avoid the reported defect. For more information, see Service Bulletin 185 .
